After leaving the Fabulous Poodles in the early 1980s, Valentino was a member of the Electric Bluebirds before joining the Hank Wangford Band at the beginning of 1984: the British country band already included pedal steel guitarist B. J. Cole (Cochise) and former Liverpool Scene/Scaffold/ guitarist Andy Roberts.

In the five years that Valentino was part of Wangford's band they recorded three albums; filmed two TV series for Channel 4 – The A-Z of C&W and Big Big Country, which attracted audiences of between two and four million at a time when The Last Resort with Jonathan Ross was being watched by 750,000; performed and wrote an acclaimed and record breaking musical: C. H. A. P. S (Cowboy, Horseriding Acting Performance Studio) at the Theatre Royal, Stratford East (their previous record was held by Oh, What a Lovely War!); toured constantly all over the United Kingdom and Europe and made numerous other radio and television appearances. These included a TV special, Christmas in Strangeways showing the band in concert on Boxing Day with a captive audience in Manchester's Victorian jail.

A part-time actor and model, Valentino has performed in West End musical theatre: in Destry Rides Again with Alfred Molina and Jill Gascoigne and in C.H.A.P.S. at the Theatre Royal, Stratford East. Occasionally he can be seen in films and commercials, usually taking the part of Clark Gable.

You're in the Groove Jackson was recorded during 1990 in Livingstone Studios in Wood Green and GibsonWood Studios in Deptford and was released in 1991 on Big Life Records. The Airplay was significant that many people[who?] thought he had had a hit but the distributors, Rough Trade Records went bankrupt the week it was due in the shops.

In 1996 You're Telling Me, which consisted of some new tracks and the best of You're in the Groove Jackson, was released by Vireo Records to critical acclaim and Valentino appeared at the 1996 South by Southwest music festival in Austin, Texas to launch the album. Again, the record company had distribution difficulties.

The 2001 release, This is Murder, consisted of new tracks and previous recordings from the earlier recordings and appeared on E.M. Records.

In 2002 Valentino won a court case against Robert Hodgens (aka Bobby Bluebell) of Scots pop band The Bluebells for unpaid royalties from his contribution to their 1993 hit "Young at Heart", co-written by Hodgens and Siobhan Fahey. Valentino's case hinged on convincing the judge that he, rather than Hodgens, had composed the song's distinctive violin part, and that the violin part made a significant enough difference to the song to be considered an original contribution.[1] The song, first recorded by Bananarama in 1983, was then released by the Bluebells with the added violin part in 1984, reaching No. 8 in the UK Singles chart. Valentino was paid a session fee of £75. However his claim against Hodgens only dated back to the time of the single's 1993 re-release and chart-topping performance on the back of a high-profile Volkswagen TV commercial. The court case attracted media attention after Valentino performed the violin part in court to illustrate his point, convincing Mr Justice Floyd to rule in his favour and award him damages of £100,000.[2] A subsequent appeal by Hodgens against the ruling was unsuccessful.[3]

In 2008 Valentino brought an action against the American R&B singer Bobby Wilson (then billed as "Bobby Valentino") and his then record label Def Jam for "Passing off, Trade Mark infringement, and breach of contract, in relation to record sales, recorded content, and artist's live performances".[4]
